To all whom it may concern.'

Be it known that I, LLOYD Gr. COPEMAN, a citizen 0f the United States, residing at Flint, county of Genesee, State of Michigan, have 'invented a certain new and useful Improvement in Grease-Capsules, and declare the following to be a fullf clear, and exact description of the same, such as will enable Others skilled in the art to which it pertains to make and use the same, reference bein had-.to the accompanyin drawings, whic form apart of this spec cation.

This invention relates to grease capsules and cu s and has to do with a grease capsule w ich has a capacity for distending itself after ithas been collapsed -to eject the grease so'that it may be re-lled and used over again.

In the drawings- Figure 1 is a longitudinal 'section of the grease cup and ease capsule.

Fig. 2 is a slde elevation of the grease capsule. l

Fig. 3 is a plan view of the grease capsule.

The grease capsule is designated a and is prefera ly made of some fabric such as mercerized silk. ,Y Within the capsule is disposed a spiral Spring b. On the outside of the capsule is a iap c by which the capsule may be pulled out. of the grease cup when the cap and plunger d are unscrewed.

Obviously when the p1 er collapses the grease capsule and ejectsuiite grease, withdrawal Vof the plunger from the capsule allows'the spring 'b,to open the Acapsule out 35 again. Hence the capsule may be' pulled out of the grease cup-'by the flap 4c and relled. Such 4capsules can be conveniently used with grease cups. in two sets. The owner of a car can'keep one set of capsules 40 filled, doing the lling at bis convenience, and as the grease exhausts from any cup, the capsule may be replaced by a filled one.

What I claim is: I

f1. A grease capsule for the purpose specified, comprisin a shell of collapsible material, means within the she." for automatically opening out the shellxwhen the cole lapsing force is removed and means` at the closed end for the purpose specified.

2. AA grease capsule for the purpose speci-- fied .comprising a collapsible shell, means wit the shell for opening same ut after the collapsing agent has been removed, and a :Hap on-the outer Vend of the capsule for the purpose specied.

3. A grease capsule,'comprising a'shell of a mercerized silk fabric, and espiral spring contained therein for the purpose specified.
